Viktor Lofgren 6271d5d544 (mq) Add relation tracking between MQ messages for easier tracking and debugging.
The change adds a new column to the MESSAGE_QUEUE table called AUDIT_RELATED_ID.  This field is populated transparently, using a dictionary mapping Thread IDs to Message IDs, populated by the inbox handlers.

The existing RELATED_ID field has too many semantics associated with them,
among other things the FSM code uses them this field in tracking state changes.

The change set also improves the consistency of inbox names.  The IndexClient was buggy and populated its outbox with a UUID.  This is fixed. All Service2Service outboxes are now prefixed with 'pp:' to make them even easier to differentiate.

Libraries

These are libraries that are not strongly coupled to the search engine's business logic. These libraries may not depend on features, services, processes, models, etc.

NOTE: These libraries are co-licensed under the MIT license.

Libraries

  • The array library is for memory mapping large memory-areas, which Java has bad support for. It's designed to be able to easily replaced when Java's Foreign Function And Memory API is released.
  • The btree library offers a static BTree implementation based on the array library.
  • language-processing contains primitives for sentence extraction and POS-tagging.
  • The message-queue library.

Micro libraries

  • easy-lsh is a simple locality-sensitive hash for document deduplication
  • guarded-regex makes predicated regular expressions clearer
  • big-string offers seamless string compression
  • random-write-funnel is a tool for reducing write amplification when constructing large files out of order.
  • next-prime naive brute force prime sieve.
  • braille-block-punch-cards renders bit masks into human-readable dot matrices using the braille block.
